Combine everything in a bowl and gently fold together, do NOT mash anything, serve with chips

***The night before, I chopped the shallot, garlic, jalapeno, cilantro, and pineapple and mixed with the lime juice and salt - I let this sit together in a bowl overnight to "marinate," and did the rest (and by the rest, I mean chopping the tomatoes and avocadoes) the next day, right before serving (I didn't want the other stuff to break down or turn brown). I think doing this the day/night before does intensify the flavors, because when I freshly chopped and juiced everything at the same time, it didn't seem to taste quite the same, but it was still good.
